WPQ range qualified question ASME IX
(OP)
Hello, all;
I'm looking for the definitive answer for which metals can be welded in the following case. A welder passes a SMAW-GTAW test on P-1 to P-1. The range qualified shows up as P1-P11,P34, P4x on the QW483 form.
I have several people who think this test qualifies the welder to weld inconel which is P-43. I disagree with their statement, since the P number is an essential variable in IX. There is some confusion due to the range mentioned above. It seems to me a separate test is required for inconel / Hastelloy, etc.
What say you all?

It will however also depend on the F number of the rod used for qualification.
A welder qualification made on P1 to P1 welded with CS filler (e.g. F4) would in theory be qualified for welding Inconel with a CS weld rod , which is of couse non-sence.
A welder qualification made on P1 to P1 using F45 filler would however be qualified to weld inconel with F45 rods.

I explained it badly in my original post. What I was disagreeing with is inconel being welded by a welder who didn't take an Inconel test, F43, just a test using F6 / F4 welding material.
Thank you both for your helpful posts, I appreciate it.
